All data from all IPS updates performed by user on R80.10 being saved in database and not removed
After a period of time in which multiple IPS updates have been performed, the database size can become very large because of unused data.
Since R80, the Security Management Server stores all revisions of IPS database. Each revision takes ~40MB. In order to prevent it from taking all of the disk space, a new procedure runs and cleans old unused IPS revisions in the DB.
